Sometimes keyp returns true even if there's no input waiting:
Welcome to Berkeley Logo version 5.5
? pr keyp
true
This seems to be due to the fact that in lkeyp, nc is declared to be a
long, but ioctl(stdin, FIONREAD, &nc) only writes an int to nc. Thus,
if the upper half happens to contain crap, nc stays non-zero on 64-bit
architectures.
Here is the patch to fix this particular problem:
